That looks like an EGR code; not the reason it's not running.

Unplug the MAF sensor and then try running it.

You may also try jumpering the fuel pump relay. Pull off the plastic cover at the fuse box (couple torx screws around the edges) and then remove relay #103. Stick a paperclip in between pins 15 and 87. Any luck?

Fuel pumps either work or they don't.

Ah, a familiar problem. My '96 850 had been pretty well, parked it overnight. All set to go to the state fair and it did the exact same thing yours is doing.
I suspected the fuel pump b/c it seemed the engine was getting a little fuel but then starving out. So I changed the fuel pump (had a used one on hand).
Did the same thing.
Changed the fuel filter (had been meaning to do that for a while anyway).
Same thing.
The fuel pump primed up (I could hear it) with key on like it's supposed to, so I assumed it was okay.
Okay, problem had to be up front somewhere.
Opened the hood, and with a little inspection, found a gaping open area in the accordian hose (air box to throttle body).
Had one on hand, replaced.
Problem solved.
Hope yours is such an easy fix.
What was happening, is unmetered air was getting into the cylinders. So I assume the engine was actualy "leaning" out due to too much air for the fuel that was being called for on start-up.
btw: if you suspect a bad MAF, there's a tutorial on this site for testing it with your multi-meter.
Good luck.

Have you checked your intercooler hose in the front? Is it possible you pulled too far into a parking space and it knocked off the hose? This exact situation happened to me and it ended up being just the hose being unplugged.

no start, fuel or spark? put key in pos II and see if you get a squirt from the fuel rail. if not, as stated, try bridging the contacts as above to check for bad fuel relay. if not the problem, then think about the cam pos sensor. IAC is involved with idle, and does not cause no start.

Hello,thanks for all the help,anyway,tried the paper clip no start,the fuel pump was buzzing,when i put the relay back in no buzzing,maybe that is how it works....anyway tried without the maf ,still no start,thinking maybe i'll check for spark? Thanks..
